What is 1/2 ( 3/5x - 8) + 7/4 ( 2/5x + 4)? (simplify the expression by distributing and combining like terms)

(1/2)*((3/5)*x-8)+(7/4)*((2/5)*x+4) = 0

1/2*(3/5*x-8)+7/4*(2/5*x+4) = 0

1/2*(3/5*x-8)+7/4*(2/5*x+4) = 0

x+3 = 0

x+3 = 0

x+3 = 0 // - 3

x = -3

x = -3

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

answer: y = -2.5x - 15
